hypomyelinating leukodystrophies

Tuesday 15 June 2004

Hypomyelinating leukodystrophies (HMLs) are disorders involving aberrant myelin formation.

The prototype of primary HMLs is the X-linked Pelizaeus-Merzbacher disease (PMD) caused by mutations in PLP1.

Homozygous mutations in GJA12 encoding connexin 47 were found in patients with autosomal-recessive Pelizaeus-Merzbacher-like disease (PMLD).
